This invention relates to cooking stoves or ranges.

An object of the invention is to provide an improved cooking stove including a number of doors capable of being adjusted about the stove-to form an enclosing cabinet and mounted in such a way that they may be moved out of the way to positions to permit the stove to be used for its usual and intended purpose.

Another object of the invention is to provide an improved stove embodying any portion or all of the useful features herein disclosed, reference being made to the drawings in which: j

Fig. 7 isa front elevationof the lower left hand portion of the stove, the door and its guides being in section.

Fig. 8 is an enlarged vertical sectional view of the lower left hand portion of the stove.

The present invention is embodied in a stove comprising the usual exposed burners 1 and grids 2 arranged in front of a rear wall 3 and at the side of a splash or Voven wall 4, which latter forms one of the walls of the upper oven to which access is obtained through a door 5. The lower portion lof the stove comprises an appropriately constructed frame 6 above which and below the burners l and the oven 5 are a number of compartments to which access may be obtained byA opening the closures 7 therefor.

The wall 4 has near its upper end a horizontal slot 8 through which projects the axle 55 9 of a pinion lO. The pinion 104 operates upon a rack 11 enclosed and supported by a channel portion 12 which may be provided by bending the top wall 13 of the oven 5 (Fig. 6'). The outer end of the axle 9 is 60 connected with a bracket 14 attached to a plate l5, the rear edge of which is connected with the front portion of a flexible wall member 15. The inner edges of the plate 15a and the wall member 15 operate adjacent to 65 the wall 4 and the opposite edges operate in a guide formed by flanges 16 projecting from a side bracket 17 attached to the right hand side of the stove (Fig. 2). The flexible wall 15 extends behind the upper end of the rear 70 wall 3 and, in the-construction shown, in front of a wall 18 rising vertically from the rear side of the stove a slight distance to the rear of the wall 3 and leaving a space 19 to` receive the flexible wall 15 when said wall is moved. 75

oted to one end of a link 22, the other end of said link 22 being pivoted to the front portion of the plate 15a adjacent to the outer end of said' plate 15a. This provides a support for the outer end of the front portion of the wall 15a when said wall is drawn forwardly be- 85 yond the front edge of the bracket 17.

Below the burners 1 and to the right of the compartment 7 an enclosed space is formed by an inner vertical wall 23, an outer vertical wall 24 and a front wall 25, said front wall 90 25 having therein a vertical opening 26. A pair of horizontal rods or shafts 27 are mounted in the space between the walls 23 and 24 and a bracket 28 is mounted for sliding momevents on each of said rods or shafts.

A door 29 has its upper and lower ends pivoted to the brackets 28 and is movable into and out of the space between the walls 23 and 24l by sliding the brackets 28 along therods 27. The upper and lower edges of the 10 'the confined space between the wa door 29 are guided by bars 30 extending from front to rear between the walls 24 opposite the opening 26. The door 29 may be drawn through the opening 26 entirely out of 23 and 24 and folded around in front of the adjacent compartments 7, as shown in Fig. 1. Or, the door 29 may be moved into the space between the walls 23 and 24 leaving free access to the front of that portion of the stove which is covered or enclosed by said door 29.

The left hand side of the stove also includes a confined space between an inner wall 31 and an outer wall 32 and a front wall 33 having therein a vertical opening 34. In the lower portion of this confined space two parallel rods 35 are supported and a sliding bracket 36 is mounted on each of said rods. A door 37 has its upper and lower ends pivoted to the brackets 36 and is operative in like manner as the door 29 so that when withdrawn and folded toward the door 29 the free vertical edges of said doors 29 and 37 are adjacent to each other. The door 37 may be moved entirely into the space between `the walls 31 and 32, the upper and lower edges of said door being operated between guides 38.

1n the upper portion of the space between the walls 31 and 32 a door 39 is mounted in the same manner as the door 37 said door 39 having its upper and lower edges pivoted to brackets 4() operating on rods 40a similar to the rods 35. This door 39 operates between guides 40b like the guides 38. When the door 39 is withdrawn it encloses thel front of the upper oven 5 and extends about to the plane o the wall 4. The doors 37 and 39 are separated by a facing strip 41 which extends the entire length of the front of the stove said strip bordering the upper ends of the doors 29 and 37 and the'lower end of the door L39.

A conned spaceis formed to the rear of the wall 3 by an end wall 42 and a rear wall 43 and in said space a pair of horizontal rods 44 are mounted. Each of the rods 44 supports a bracket 45 which brackets are capable of sliding movements along the rods 44 and have their ends pivoted to the upper and lower ends of a door 46 which is capable of being withdrawn from the space in front of the rear wall 43 and folded around against the bracket 17. When this door 46 is folded around against the bracket 17 it forms a closure or wall for the upper right hand portion of the stove, as shown in Fig. 1. A

supplemental'door 47 is pivoted to the front' edge of the door 46 by double hinges 48 which permit said door 47 to be folded to the position indicated by dotted lines in Fig. 3 in which the outer side of the door 47 is against the outer side of the door 46; 0r, the door 47 may befqlded around to the front of the stove so as to cooperate with the door 46 and the wall 15 to form an enclosure for the space above the burners 1. When the door 47 is extended around to the front its free vertical edge is adjacent to the free vertical edge of the door 39 and is above the facing strip 41 while the lower edge of the door 46 is above a rearward extension 49 of the facing strip. Thus, the door 47 may be folded rearwardly from the position shown in Fig. 1 so as to lie against ther outer side of the door 46 and the door 46 may then be swung outwardly and moved inwardly into the confined space in front of the rear wall 43. The opening through which the doors 46 and 47 are moved into and from the con! fined space in front of the wall 43 lmay be closed by a door 50 having its rear edge hinged to the wall 43.

A latch device comprising an angular bracket 51 has one end hinged to the inner front edge of the door 46. When the. door 47- is folded rearwardly. against the outer side of the door 46 this latch bracket 51 may be swung around to enclose the front edges of the doors 46 and 47 and latched to the latter by a spring latch 52 of any appropriate construction. v

From the foregoing it will vbe apparent that when it is desired to enclose the stove so as to obtain a`V cabinet device it is only 'necessary to/withdraw the doors 29 and 37 and fold them to the front of the stove and also to withdraw the doors 39, 46, and 47 and -fold them about the upper end of the stove in the obvious manner. Preferably, the flexible wall 15 is drawn forwardly before the walls 46 and 47 are folded about the upper end of the stove. When it is desired to open the cabinet thus obtained so as to use the stove for its intended purpose the doors may be opened and moved out of the way into their respective enclosures in the manner descrlbecl.
